CAR-HEATING SYSTEM.

Specicaton of Letters Patent.

Patented July 16, 1912.

Application filed-.Tune 11, 1909. Serial No. 501,502. Y

To all fr0/0m t may concern:

Be it known that I, WILLIAM L. GARLAND, a citizen of the United States, residing at Llanerch, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Car- Heating Systems, of which the following is a full, clear, and exact description, such as will .enable others skilled in the art to which it appertains to make and use the-same.

This invention relates to heat-ing systems and more especially to systems. installed in metal cars.

One of the objects is to provide a practical system of this character' in which the metallic wall of the car will be positively heated,

Another object is to provide a system in 'which the air contained within the space between the outer and inner sheathings will be heated.

Furth-er objects are to provide a system of this character which will be inexpensive and simple in its construction; which may be readily installed in cars without requiring any alteration in their construction; and which will be en'icient in use.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the feat-ures of construction, combinations of elements and arrangement of parts which will' be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following` claims.

In the accompanying drawings, wherein is shown one of various possible embodiments of the invention, Figure 1 is a diagrammatic perspective View illustrating the location of the heating system with respect to the Hoor of the car body; Fig. 2 is a vertical, sectional view of a portion of a car; Fig. 3 is a plan view of Fig. 2; Fig. 4 is an enlarged sectional View taken on the line of Fig. 2.

As tending to a more ready understanding of certain features and aims of this invention, it may here be noted that in cars constructed of metal it has been found that in cold weather the inner sheathing of the side walls is likely to be cold, due, largely, to the heat conducting powers of metal, even though the interior of the car is comfortably heated. The window sills, also,

are likely to be cold, and passengers seated next the windows are thus often uncomfortably cold, due to the proximity of these chilled surfaces. The above objections and others are obviated by means of the system hereinafter described,

Referring now to the drawings, 1 indicates the flooring of the car body and 2 and 3 indicate the outer and inner sheathing, respectively, of one of the side walls, the window-sill being shown at 4.

5 indicates car seat-s of any approved construction, one of which is preferably positioned adjacent each window, as usual in car construction.

A train pipe G adapted to be connected to a source of heated medium, such as the steam from a locomotive, extends lengthwise of the car as is usual in train heating systems, and is connected by a branch pipe 7 to a suitable radiator 8 which, in the present instance, is represented as consisting of piping extending preferably from the center of the car toward each end thereof, and returning to a pipe 9 which communicates with a suitable steam-trap 10. A valve l1 preferably located in the branch pipe 7 regulates the liow of the heated medium to the radiating system. The radiating pipes 8 are placed adjacent the inner sheathing of the car wall, as clearly indicated in Fig'. 4, being preferably arranged with the portion which is connected to the source of supply above the portion which communicates with the steam-trap. j

At different points of the radiating system, preferably between each of the seats as indicated in Figs. 2 and 3, a heat conducting member such, for example, as a large metal block 12, is positioned between the upper pipe of the radiator and the inner sheathing of the wall, being in intimate contact with each of these members. As shown in Fig. 4 the block is preferably recessed as at 13 t0 receive the piping of t-he radiating system, and the parts may be maintained in position in any suitable manner, as, for example, by means of a strap -14 secured in position by suitable fastening means 15, such as screws, which extend through the block 12 and through the inner sheathing 8, as indicated in Fig. 4. It will, of cours-e, be understood that any other suitable heat-conducting member could be employed in place of the block and that any other suitable fastening means could be utilized, although many Yadvantages reside in said car connected with the wall `and said the form shown.

The operation of the system, which should be largely obvious from the above descrip. tion, is as follows: When the steam is ad` mitted into lthe radiator, the conduits" through which it iiows will become'heated. This heat will not only be radiated therefrom to warm the air within the car, but

will be `communicated by conduction through the blocks 12 to heat also lthe inner sheathing 3 of the wall, through which it will be conducted to the ,sills of the windows,`

thus insuring that these portions of the car will be positively heated. It will also vbei understood that the air contained between the inner and outer sheathing will be warmed, thus assisting in attaining the desired object.

It will thus be seen that the objections above-,noted are fully overcome by means of the system herein described. It will also be seen that the apparatus may be installed in any car without the necessity 4of altering the same to any appreciable extent, and that the system will be simple in construction and eificient in operation.

As :many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from Lthe scope thereof, it is intended that all matter contained in I,the above .description .or shown inthe accompanying drawings shall `be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language -used in the following claims is intended to cover all of the generic ,and specific `features of the in vent-ion herein described, and all statements of the scope of the invention which, as ya matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

. 1. -In a heating system., combination withga passenger car body having a metallic inner wall, of a plurality of seats within said car,a conduit within the car adapted cto beeonnecteditoasource of supply of heated medium `through which said medium is adapted to iiow, and a plurality of metallic blocks one between each pair ofthe seats of a heated medium and through which said medium is adapted to flow, a ret-urn conduit substantially parallel'thereto, and a'metallic member fitted lbetween and in contact with said first mentionedconduit only and .sa-id sheathing.

3. In a heat-ing system, the combination, with a Vmetallic car body provided with a window in one of its walls, of a windowsill associated therewith, a conduit within said car adapted to be connected to a source of supply of a heated medium, and intermediate means comprising a relatively large block of heat conducting material secured thereto between said conduit and windowsill whereby heat is transmitted from one to the other by conduction.

4. In a heating system, the combination with a car Vbody provided with a. window in one of its walls, of a window sill associated therewith, a conduit within the car adapted to be connected to a source of supply of a heated medium and through which said medium is adapted to flow, and metallic Ymeans operatively associated with said conduit and the wall of the car adjacent said sill for causing the sill -to be heated by the medium flowing through the conduit.

5. In ia 'heating system, the combination with a car body provided with a plurality of windows in one of its walls, a. window sill associatedwith each of said windows, a conduit within the car adapted to be connected toa source of supply o-f a heated .medium and through which said medium is adapted to flow, .and metallic means interposed between said conduit and said wall adjacent each of said windows.

"Intestimony-whereof I affix my signature, in the presence o-f two witnesses.
